Y134 is a selective and orally active oestrogen receptor (ER) modulator (SERM), exhibits potent antagonist activity at ERα and ERβ. Y134 shows 121.1-fold selectivity for ERα (Ki=0.09 nM) over ERβ (Ki=11.31 nM). Y134 inhibits oestrogen-stimulated proliferation of ER-positive human breast cancer cells.

Description

Y134 is a selective and orally active oestrogen receptor (ER) modulator (SERM), exhibits potent antagonist activity at ERα and ERβ. Y134 shows 121.1-fold selectivity for ERα (Ki=0.09 nM) over ERβ (Ki=11.31 nM). Y134 inhibits oestrogen-stimulated proliferation of ER-positive human breast cancer cells[1].

IC50 & Target[1]

ERα

0.09 nM (Ki)

ERβ

11.31 nM (Ki)

In Vitro

Y134 exhibits potent antagonist activity at ERs in CV-1 cells cotransfected with plasmids containing ERα or ERβ and oestrogen-response element-driven luciferase, with IC50ERα and 2.94 nM for ERβ[1].
Y134 (0.01 nM-10 μM; 6 d) inhibits the oestrogen-stimulated ER-expressing breast cancer cell (MCF-7 and T47D) proliferation[1].

Cell Viability Assay[1]

Cell Line: MCF-7, T47, MDA-MB-231 cells
Concentration: 0.01 nM-10 μM
Incubation Time: 6 days
Result: Suppressed oestrogen-stimulated MCF-7 and T47D cell proliferation.
Showed no effects on MDA-MB-231 cells, except some cytotoxicity was seen at high concentrations.
In Vivo

Y134 (1-3 mg/kg/day; p.o. for 3 days) abolishes the E2-induced mammary gland terminal end bud (TEB) outgrowth in ovariectomized rats. Y134 inhibits uterine cell proliferation induced by E2 in a dose-dependent manner[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Four-week old female Sprague-Dawley rats were received ovariectomy[1]
Dosage: 1, 3 mg/kg
Administration: P.o. daily for 3 days
Result: Abolished the effect exerted by E2 in a dose-dependent manner.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
